SPECIFICATION forming part of Iietters Patent no. 629,639, dated July 25, 1 899.

A Application filed September 28, 1897. Serial No. 653,298, (No modeld I To all whom it may concern.- Be it known that we, WILLIAM WILKlNs and NELSON G.'POE, citizens of the United States, residing at Greenville, in the county in cultivators of the class usually employed for cultivating cotton, corn, and othercr'opsgl and the objects of our inventionjare to simplify the construction-of the cultivator, re-

duce the cost of its manufacture, and enable the plow-feet to be attached to the bea'min a variety of positions and arrangementswith reference to each other, thereby adapting the cultivator to be used under varyin g conditions and to accomplish diiferent kinds of work,

In the accompanying drawings, Figure l is a top plan view of our improved cultivator. Fig. 2 isa side elevation of the same. Fig;

3 is a detail view of the beam.

In the construction of our improvedculti- Vator We employ a beam 0., which'is'c'omposed of a single straight bar of steel or iron of suitable length, breadth, and thickness. At

the front end of the bar'are formed the usual,

hook band the link 0 for the attachment of the singletree, and the rear end of the beam is upturned at an angle of about thirty degrees for a considerable distance to form the stock cl, to which are bolted the lower ends of the handles e by means of a pair of bolts f, which pass through openings made in the upturned stock and in the lower ends of the handles. A rung g connects the handles at I a suitable point and serves to spread them;

apart.

It will be observed by reference to the drawings that the thickness of the handles 5 is steadily reduced from their outer to their lower ends, so that the lower portions of the handles, which are adapted to bearagainst the upturned rear end of the beam, are so re- 1 duced in thickness that they are capable of being bent to lie against the opposite sides of the upturned rear end of the beam and are held in position by the bolts f,'which construction of the beam and handles enables the latter to be fashioned and secured to the 5b beam without being cut across or diagonally with the grain of the-wood, the handles being sprung. or bent into shape at their lower ends to conform to the upturned rear end of the beam, and hence they are not weakened by cuttingor shaping them in the manner now usual in the construction of this class.

implements of Beginning at a point near the center of the I beam and extending to near the upturned rear end thereof area series of six bolt-holes h,fwhich are spaced equally distant apart and'serve for the attachment and adjustment of the cultivator feet or stocks t' 70 l. Y

The cultivatorfeet or stocks t' Z, are. each 7 made of a single piece of bar iron or steel of the same breadth and thickness as that ern= ployed inthemanufacture of the beam, and p I said feet or stocks 1 l are adapted to work on opposite sides of the beam, each having the angular wing m, the standard it at the rear 'end thereof for the attachment of a suitable. cultivator-tooth, and theforwardlyextending 1 arm 0, adapted to lie snugly against one side of the b'e'amjand having a pair of bolt-holes which are adapted to register with a pair of the bolt-holes'with which the'beam' is provided, whereby the cultivator stocks or feet can be readily attached to or removed from the beam or secured at any desired adjustment'thereon by means of bolts p. The wing m of the stock or foot Z, which is adapted to operate on the left-hand'side of the beam, is

considerably longer than the wing of the stock or-fo0t i, which is adapted to operate on the right hand side of the beam, and when the said stock 71 is secured to the beam by the 1 foremost pair of bolt-holes in the latter and the bolts and the stock or foot Z is secured to the beam by'employing the next pair'of bolt-holes, as shown in the drawings,'the

standard of the'stock I will be at a-distance inrear and to one side of the beam and the standard of the stock i will be considerably .in advance of said standard of said stock 5 and tothe opposite side of the beam, so that the cultivators or teeth attached to said standards will be arranged in a diagonal line with relation to the length of the beam at about forty-five degrees, one in advance of the rear end of the beam and the other at a correspending distance behind the rear end of the beam, which diagonal line 11:, Fig. 1, is iutersected by a line 1 3 Fig.2, drawn longitudinally through the center of the upturned end of the beam to which the handles are attached, whereby the draft is balanced on opposite sides of the beam and all side strains on the handles are obviated, the angle of the handles and their position on the rear end of the beam being such that they are subjected onl'yto longitudinal stress and all side stress is obviated. This enables us to dispense with braces for the handles withontat all impairing their strength or durability,.and, moreover, this arrangement'of the handleswith relation to the line of draft renders it much easier for the plowman to control the implement and materially reduces the necessity,

for muscular eifort. The stock or foot kis also made of a piece of ban iron or steel of similar size to that employed for the beam; butthe said stock or foot It; is simply formed of the arm, adapted to be bolted to therear portionof the beam atthe rearlnost pair of bolt-holes, and the standard r. This standard is shorter than the standards of the stocks '1' 1, so that the cultivator-tooth attachedtoit will, not run so deeply as the cultivator-teeth attached to the standards of the outer feet or stocks, and the draft will be greatest at the outer cultivator-teeth,which arrangement and construction is advantageous for the rea- Son that it causes the implement to run much steadier,rednces side strains, and reduces the labor of the lowman. a

It will be noticed that the cultivator-tooth attached to the center stock 76 operates in the diagonal line w, before referred to, when the stocks are arranged as shown in the drawings,

which is the normal and nsualarrangement and the one most frequently employed; but it will be understood, as before stated, that the cultivator-stocks are capable of attachment to the beam and of operation in a, variety of arrangements, and one or more of them may be discarded, if preferred or as may be rendered necessary by the Work to be accomplished.

Having thus described our invention, we claim-- 1. The cultivator comprising the beam formed of a straight fiat bar ofmetal, having the upturned rear end and the series of equally-spaced bolt-holes h, extending from near'the rear end toabout the center of the beam; the handles boltedtoithe upturned end of the beam; the side stocks 1', Z, each formed of a single fiat bar of metal, bent angularly to form the arm 0, angular wing m, and downcurved to formthe standards 9t," the win g of the stock 2' b'eingmaterially shorter than the wing of stock Z; and thecenter stock 7s, formediof a metal bar adaptedto be bolted to the beam at the real-most pair of bolt holes, and dow'nturned to form the standard 9", said standard being shorter than the standards n, substantially as described.

2.1m a cultivator,theabeam,the central cultivator-stock having thestandard, the side cultivator-stocks having the standards of equal length and of greaterlength than that e of the center, stock, whereby the side culti vator teeth or plates will run deeper than the toothor plate of the centercultivator, for the purpose set forth, substantially as described.
